Multi Generation Content: Battle Stat Changes | So you've seen moves like "Amnesia" and "Screech", eh? Well, you've been
wondering what they really do haven't you? In this guide I'll be
explaining what these moves actually do to your stats.

First of all, the moves themselves increase or decrease the stats in
'stages' which have a particular multiplier to make a whole number that is
your stats. The following table has these multipliers:

Stat Stage

8/2

So what does this all mean?

Well, each one of the stat-boosing moves will raise/decrease a stat by 1 or
2 stages. This can make your Pokémon a lot stronger, or a lot weaker in
battle. These are shown by the terms:

x rose! - 1 stage increase

x fell! - 1 stage decrease

x sharply rose! - 2 stage increase

x harshly fell! - 2 stage decrease

Where x = stat

Let's say you have an Infernape with 300 Attack. You get it to use Swords
Dance (2 stage Attack increase) so we'll have:

300 * (4/2) = 600 Attack!

You see, using these moves can make your Pokémon a lot stronger. Just here
Infernape's Attack rose by 300 in just one move!

But before you start trying to make your Pokémon's stats hit the roof in
battle, let's just one thing straight; you can only have a maximum of 6
boosts to one stat. Whether that's three Nasty Plot boosts, six Calm Minds,
whatever, you can only have 6 boosts maximum. Vice versa, you can only have
your stats reduced by a maximum of six stages, too.

Another thing to remember is what stats are effected by these. The following
stats are boosts or reduced by the moves:

Attack

Defence

Special Attack

Special Defense

Speed

Of course, HP is different so it is reduced by other attacks in the form of
damage.

Some abilities also increase or decrease stats in battle. Most of these need
certain effects to be in battle like Sandstorm, Sunny Day, Hail and Rain
Dance. Some, like Intimidate, need the Pokémon to just be brought out
against another Pokémon. Others need the use of an item, another uses the
opponent's stats to calculate its own.

What do Double Team, Sand Attack and the like do then?

Double Team and Sand Attack affect different stats called Evasion and
Accuracy. Evasion determines whether your opponent is going to be hit; it's
more of a defensive move, whereas Accuracy determines whether you are going
to hit your opponent; it's more of an attacking move as it affects the
attacks of your Pokémon's base accuracy.

Like the other stats, Evasion and Accuracy go up in stages and yes, 6
maximum for both of them. The following table shows the multipliers for both
Accuracy and Evasion:

Accuracy/Evasion Stage Increase/Decrease

Both Accuracy and Evasion use these multipliers. They do not have separate
ones. Evasion can be both increased and decreased by using these kinds of
moves but Accuracy, however, can only be lowered. There are no moves yet
that allow you to increase your Accuracy, though there are various items and
abilities.

So there you have it, a crash course on Stat-up and Stat-down moves. Hope
you enjoyed the article; you may now turn off your monitor.
